[Moose-dev] Roassal DNU getting the element from an RTArrowedLine

Hola, in part of the code of LRP I work with arrows, and I need to get the shape, but this triggers a DNU. I guess I need to set something on the arrow before I can get the element, or get it via another route. What should I do? Relevant code below: arrow := RTArrowedLine new color: trans color; edgeFrom: efrom to: eto; withOffsetIfMultiple. element := arrow element. Gives me: RTElement(Object)>>doesNotUnderstand: #to RTShorterDistanceWithOffsetAttachPoint(RTAbstractShorterDistanceAttachPoint)>>basicStartingPointOf: RTShorterDistanceWithOffsetAttachPoint>>basicStartingPointOf: RTShorterDistanceWithOffsetAttachPoint(RTAttachPoint)>>startingPointOf: RTLine(RTAbstractLine)>>updateFor:trachelShape: RTLine(RTShape)>>trachelShapeFor: RTArrowedLine>>trachelShapeFor: RTElement(RTShapedObject)>>addShape: RTArrowedLine(RTShape)>>element LRPProgramVisualization>>buildTransition:withElements:forView: ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile
